Answer:
total cost incurred 2,250,000
Explanation:
From the inventory identity we solve for the added materials:
[tex]$Beginning Inventory + Purchase = Ending Inventory + added[/tex]
Beginning raw 390,000
purchase 890,000
ending raw (340,000)
added materials 940,000
Then, we solve for the cost adeed during the period, which are the cost incurred during the period:
added materials 940,000
labor 670,000
applied overhead 640,000
total cost incurred 2,250,000
